You can test the battery in or out of the car with a pocket multimeter. Less than 12.5v means it's weak and much lower means it's bad. As to why jump starting no longer works, tell us more. You jumped it twice on the street from another car, then jumped it at home from another car, and the next day you jumped it from another car on the street and it just clicked? Is that the sequence?

The battery probably failed when some of the plates lost their mechanical strength and shorted to one another. This happens due to age, crappy manufacturing, or especially deep discharging.

Conventional lead acid car batteries (not marine deep discharge lead acid batteries) are not designed for a deep discharge, especially a prolonged discharge. Even leaving one of these batteries in a shallow state of discharge for just a short period of time will take capacity out of them as the un-reversed sulfate deposits harden. Car batteries are designed to always be fully charged. Their design basis is to only provide a lot of energy for a very short period of time to start the car and then be immediately recharged. If for whatever reason, the battery is found to be in a state of deep discharge, it is probably permanently damaged and will fail eventually prematurely. At best, if your lucky, the deep discharged battery, not immediately recharged, will no longer have its design basis capacity.
